To all whom it may concern:

Be it known that I, JULIUS C. PRoEBs'rEL, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented a new and useful Recording and Duplicating Device, of which the following is a specification.

The principal object of the present invention is to provide a recording or duplicating device for the use of lecturers in keeping the notes of a speech in view, or for the recording of notes, bills, cheeksor other memorandum, and for providing duplicate slips or checks of any desired number which may be torn ofl in case of a memorandum of sale, one to be given the purchaser and the other to be presented to the checker or cashiers desk.

A further object of the invention is to provide a device of this class in which all of the parts may be arranged within a suitable box or casing that may be made of various forms,

and in some instances may be in the guise of a book for the convenient use of a lecturer or minister.

A further object of the invention is to provide a device of this class in which all of the operating parts,record strip and the like may be readily removed from the casing for the use of the bookkeeper, while another apparatus containing fresh strips is placed in the case for the use of the salesman or clerk.

Astill further object of the invention is to provide a device of this type in which all of the parts are concealed and protected by a detachable cover or plate that is provided with a suitable opening through which access may be had to a portion of the strip or strips for the purpose of making a record, or for displaying a record previously made.

A still further object of the invention is to rovide a recording or duplicating device in which the strip or strips are so arranged as to be fed or ejected by a thumb or finger actuated roller within convenient reach of the user.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in certain novel features of construction and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size and minor details of the structure may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accon'ipanying drawings: Figure 1 is a longitudinal sectional view of a recording and duplicating device constructed in accordance with the invention. Fig. 2 is a detail perspective view of the inner frame and the parts carried thereby removed from the easing. Fig. 3 is a transverse sectional view of the device on the line 3 3 of Fig. 1 looking in the direction indicated by the arrow. Figs. 4, 5 and 6 are views corresponding to Fig. 1 illustrating modifications. Fig. 7 is a. detail perspective view of the detachable upper casing. Fig. 8 is a detail perspective view of a portion of one of the upper strip carrying rollers, showing, also, a portion of the paper or cardboard tube to which the inner end of the paper strip is secured.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In the construction shown in Figs. 1, 2 and 3, the casing 10 is made in the form of a book, one of the covers 11 being hinged, as shown in Fig. 3, and being foldable down over the working parts to conceal the same from view, and this type of casing is used in all cases where the device is employed for the purpose of keeping notes for the delivery of a lecture, sermon or speech, where the device may be placed on pulpit or speakers stand, and operated from time to time as may be necessary in order to expose portions of the notes to View during the delivery.

Arranged within this casing is a removable frame of the character shown in Fig. 2, and comprising a pair of parallel side plates 15 which are connected to each other by a plate 16 that constitutes a platen and over which the sheet or sheets of paper are passed to be exposed to view or for the purpose of making a record. In the construction shown in Figs. 1 and 3, a record strip 16 and two separate check strips 17 and 18 are employed, and these are guided over the platen 16 in the manner hereinafter described, while between these sheets are arranged sheets of carbon or transfer paper 20, the edges of the carbon paper being turned down over the sides of the plates 15 and being confined in place by strips 21 mounted on pins 22 projecting from the plates 15 and held in position by pins or screws 23 which enter grooves 24 formed in the strips 21, the side walls of the grooves being inclinedin order that the heads of the pins or screws may exert a slight cam or wedging action on the strips and thus tend to firmly bind the carbon sheets in place.

' Near one end of the frame the two plates 15 are provided with 0 enings 25, 26 and 27,

thelower portions of t ese openingsformingbearings for the supportof the end pintles or shafts 28 of a number 'of roll ers L29, 30'and fend toatube 33, and thenwi'nding the strip 'thereon,"afterwhich the assembled strip and 't1ibe1ma'y be'readilyslipped on toany one of th'erollers' and may be rotated therewith, or as shown in the present instance the two strips '17 and'16 may be secured to a single :tube which is'place d onthe roller'29, while the remaining strip 18 is placed separately on the roller 30, there being as'manystrips as necessary,"and the number of rollers being increasedaccordingly. I i

'All" of the strips 'pass over their carrying rollers, over" the platen 16, and thence to and ever a roller 36, under a roller 37, and over a l ro 1ler"3 8, these several rollers firmly engagingwith the upper strips and'serving when rotated to feed the same forward. The main record strip returns to the roller 31, 'j and'is wound thereon, while the other strips 17"an d 18 are moved upward through a "ClIS cha'rge slot 40 in a cover plate 41, the end of this cover plate havinga sharpened edge 42 "which may be'employedfor the purpose of "severing the projecting portions of the strips, and when the device is used by a salesman, one'of the severed strips may be handed to the customer as a receipt, while the other goes to'the cashier with the money received "for payment. I I

I The'several rollers 29, 30 and 31 are provided with thumb disks 43 which project "slightly "through. openings formed in the oover plate 41, and have roughened or milled peripheries for convenient engagement by the thumb or finger of the operatorfand in I "use it is merely necessary to turn the operat- 1 ing disk of the roller 31 in order to cause the record strip to be wound thereon, this movement being transmitted through the strip to 1 the several rollers, 36, 87 and 38 and causing f the remaining strips to be fed forward across the platen and out through the discharge slot.

The other rollers may be turned if necessary in order to position the strip or to make'alterations, if desired, and such alterations will, of course, be recorded on the strip that remains within the casing.

The protecting plate 41 has depending fianges'45 which extend down close to the inner walls of the main casing 10, and this plate serves to'conceal and protect all portions of the device. The protecting plate is provided with'an opening 46 immediately 'above'theplaten 16,so that a record may be convenient y made, or a record previously niade ona strip *maybe'b'rought into "view.

iIn'the construction shown in Eig. 4 three separ'ate check strips 17, '17 and 18 are used, and these are mounted on separate rollers arranged within the frame and located in thisins'tanc'e under the platen. The construction other wise'remain'sthe same as that previously described, with the exception that an' auxiliary guiding roller 50 'is employed for the purpose of directing the strips in the proper course.

"In'the constructionshown'in Fig. 5 the record strip is usedwithout any check strips and is inerelywoundon one roller as'it is unwound from the other. This construction is especially adaptedfor the use of lecturers,

ministers, and other speakers for the pur fpo'se of holding notes which may be brought into view during the delivery of aspeech.

In the construction shownin 'Fig. a single check strip is employed 1n connection with" asingle' record strip and in this instance only two of the feeding rollers are employed for'thetransinission of movenient'f'rom the record strip to the'check strip.

In order to secure the necessary friction of the rollers and prevent the same from turning loosely, the side plates 15'fare connecte'd t'ogetherby a tensionro'd 6O which may be adjusted for the purpose of forcing the side plates against the ends of the rollers and friotionally binding the same in order to hold the strips as taut as maybe desired.
